Buckling and postbuckling of composite structures

Composites, 1995
Abstract The postbuckling behaviour of a flat, stiffened, carbon fibre composite compression panel has been studied, theoretically and experimentally. The panel had a collapse load in excess of three times the buckling load. An initial failure mechanism leading to eventual explosive collapse of the panel is identified and the damaging stress ...

Buckling and Postbuckling of Prestressed Sandwich Arches

Journal of Structural Engineering, 1993
A nonlinear finite element model is developed to investigate the stability behavior of a novel type of structure, namely prestressed sandwich arch. A prestressed sandwich arch is formed by buckling its individual layers into an arch shape and assembling them as a sandwich composite.

Buckling and Postbuckling Behavior of Shallow Shells

AIAA Journal, 1976
advent of lighter weight, higher strength materials, and optimization has introduced thin walled structures in which buckling precedes failure. Hence stability has become one of the main governing factors in the design of shell panels. Archer et al. have found the buckling loads of shallow spherical shells adopting finite-difference method.

Finite Element Buckling and Postbuckling Analyses

Buckling and Postbuckling of Composite Structures, 1994
Abstract An overview is given of the finite element buckling and postbuckling analyses of composite plates. Discussion focuses on finite element formulations of the prebuckling, bifurcation buckling and postbuckling responses; sensitivity analysis; application of reduction methods and otherrecent computational enhancements.

Buckling and Postbuckling of Orthotropic Plates

AIAA Journal, 1976
Theme T stability is considered of flat rectangular plates when in-plane biaxial loads are applied. The in-plane and bending elastic properties are orthotropic and the plate axes of symmetry and the elastic axes of symmetry coincide. Both the initial buckling and the reduction in stiffness occurring at the instant of buckling are considered.

Stability, buckling, and postbuckling of elastic structures

Meccanica, 1975
This paper is the continuation of a research on the stability and postbuckling behaviour of elastic structures; in the first Part [n. 4, Vol. X, 1975 of this Journal], the potential energy of elastic tridimensional bodies has been defined in a suitable configuration space, and its properties of regularity have been studied.

Buckling and Postbuckling of Heavy Columns

Journal of Engineering Mechanics, 1987
The standing column is one of the most basic elements in the theory of structures. Its stability due to the combined effect of compression and nonzero density has been studied for the fixed-free and fixed-fixed situations. To complement this, accurate stability boundaries are compared with existing data, and postbuckling characteristics are found.

Buckling and postbuckling behavior of delaminated sandwich beams

Composite Structures, 1992
Abstract An investigation was performed to study the buckling and postbuckling behavior of sandwich beams containing lengthwise and depthwise through-the-width delaminations. An analytical beam model was developed to predict the buckling load of the beam and to describe its postbuckling response for arbitrarily situated delaminations and various ...

Delamination buckling and postbuckling of composite cylindrical shells

36th Structures, Structural Dynamics and Materials Conference, 1995
A higher-order shear deformation theory is developed for accurately evaluating the transverse shear effects in delamination buckling and postbuckling of cylindrical shells under axial compression. The theory assures an accurate description of displacement field and the satisfaction of stress-free boundary conditions for the delamination problem.
